Motorized Slide Housing for Smooth Flexible Display Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with manual slide modules face challenges in smoothly transitioning between slide-in and slide-out states due to repulsive forces from flexible displays and manual slide modules, leading to user inconvenience and non-intuitive operation.
Innovation Solution
Incorporating a drive motor with a pinion gear in the first housing and a rack gear in the second housing, controlled by a sensor module and processor to automatically manage the slide-in/slide-out operation based on user input, providing an intuitive and convenient sliding experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual slide module is used for slide-in/slide-out operation, then the device structure is simple, but the sliding operation is not smooth due to repulsive forces from flexible display and manual slide module
Solution Approach 1:
The patent replaces the manual slide module with an automated drive module consisting of a drive motor, pinion gear, and rack gear. The drive motor automatically drives the second housing to slide in and out of the first housing, eliminating the need for manual sliding operations and the associated repulsive force issues while maintaining structural simplicity through integrated automation.
2Ease of operation
If a drive motor with pinion gear and rack gear is used for automatic sliding, then the sliding operation is smooth and automated, but the device complexity increases
Solution Approach 1:
The patent merges the drive motor, pinion gear, and rack gear into a single integrated drive module that is disposed within the inner space of the electronic device. The pinion gear is engaged with the rack gear structure, creating a compact automated sliding mechanism that reduces overall device complexity while providing smooth automated sliding operation.
3Device complexity
If uniform triggering method is used for slide-in/slide-out, then the control logic is simple, but the user experience is tedious and buttons are hard to recognize
Solution Approach 1:
The patent implements different triggering methods for different operational states: a first triggering method using a physical button for slide-in operation, and a second triggering method using a gesture input for slide-out operation. This localized differentiation of control interfaces provides intuitive and varied user experiences while maintaining manageable control logic through state-based selection.
